I have the RP5-GM11 steering wheel control module. I had a similar instance with my '08 Silverado. Gauges went crazy, shut the truck off and restarted without any issues since. A GM tech told me it could be a bad ground somewhere. Dunno, as long as it doesn't happen again. Thanks for the replies.

What is the U1000 code? Will it show on a regular OBII scanner?
